It's an old waifu gacha collection game that used to be popular since its released last 2016 by Shift Up where you as the player will represent as an Archfiend candidate to contest the position for the new ruler of Hell. And you need to collect waifus to make this work.
I'm not going to dwell too much on the gameplay since it's no longer available after they announced its shutdown last September 21, 2023. The reason was not specifically stated but we could guess it's probably declining sales or a new focus on diverting resources for their other games Nikke. Shift Up is also the developer for the Stellar Blade.
I know this is OLD news, but this got me thinking about how much I've been planning to spend more on Nikke: Goddess of Victory gacha game. I'd like the idea where even if the game is gone, I could still comeback to the content that got me invested on the game in the first place which is the story... and waifus.
Memorial Version:
You get to keep the app with all the progress saved without the gameplay functions. The app is now a library for story events and waifu gallery and is still up at the time of this writing.
Why is this a good thing? it's not really a common practice for mobile games to release anything along the lines of a memorial version. When a game shuts down, there's not much incentive to keep the servers running. A game would probably just be unavailable and the money your poured into it gone. I've had this experience with Immortal Soul: Black Survival where my paid skins went away after the announcement of it shutting down.
I had trouble recovering my own account after the phone I used to play the game got corrupted so searched for accounts on reddit willing to share their gallery which allowed me to access content I only dreamed of unlocking with consistent months of grinding in the past. The account I borrowed must've been a whale to collect this much waifus. I'm predominantly a Free to Play gamer but there are occasions when moving tiddies are worth gambling for. You'll never understand.
You've got to get used to not owning your games they said. The first thing that came to mind when I heard those lines were traditional mobile gacha games on web2 aren't so different from web3 in that regard. Anyone can tell me that this piece of string of code is an NFT I own but if the game shuts down, what do I have to show for? It's not like web3 games will release their codes in public so that the community can take up the torch and run their own versions to keep the game alive when the main dev decides to throw the community under a bus... or the dev gets hit by a bus. It can happen, I just don't think it's often.
You can check the video linked at the bottom of the post to see what the gameplay looks like.
Thanks for your time.
